  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Calgary Area Meetup is set for Saturday July 12th at 10am. The signup thread is here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

    How to make hole for taper pin ?

    It might be worth thinking about step drilling the hole if you have drill bits in small enough increments. (Perhaps 3 steps equally spread over the depth.) This will considerably lower the stress on the reamer as it cuts the larger end of the taper. It may not be an issue with a 6mm pin but is...

    UHMW

    One consideration that may not apply to this application ... if high precision and/or consistency is required between parts. Letting the part(s) "age" for a few hours before final turning is helpful. This was learned when making go/no-go gauges. Dimensions would creep a couple thou overnight...

    Another runner - Howell V-Twin

    No, it’s just going sit pretty and get a run once in awhile like all its “stable mates”. It’s running on straight methanol. It burns clean, smells like an old sprint car and doesn’t gum up the works. It’s a little fussy to start when dead cold but the tiniest bit of warmth and it starts right...

    Another runner - Howell V-Twin

    Thanks everyone for the kind comments. Craig - no I haven't checked the speed (my old Royal optical tachometer is out-of-service). I am pleased with how smooth it is throughout the range though. When the timing was too advanced to idle it hummed along at a frightening clip. Now that a better...

    Machine Not sure I need a drill press anymore

    If you are worried about space ... How about using your wood skills to build a storage cabinet "around" the drill press stand to use the space under the table. Something with lots of small drawers on casters? Oh, and No, don't get rid of that drill press ... you'll be sorry.

    Another runner - Howell V-Twin

    Happy with how the latest shop project turned out. It's a 32cc 90 degree V-Twin to a design by Jerry Howell, a well known model builder and designer. Although Jerry is no longer with us, his son still makes the collection of drawings and hardware available. It was a fun build to a very nice...
